# Feature Flags

## Подключение

### Maven

```xml

    ru.romanow

    feature-flags

    ${feature-flags.version}

```

### Gradle

```groovy

testImplementation "ru.romanow:feature-flags:$featureFlagsVersion"

```

## Реализация

Классы, которые необходимо перезагружать при обновлении флагов:

* Класс `Features` (`@ConfigurationProperties(prefix = "features")`) и beans, куда он autowired.

* Beans, помеченные аннотациями `@ConditionOnFeatureEnabled`, `ConditionOnFeatureDisabled` и

  `@DefaultFeatureImplementation`.

* Классы, где есть `@Value("${features.*})`.

Способы получения обновленного конфига:

* Файл на host-машине:

    * classpath (by default) – не контролируется;

    * `/opt/features.yml` (контролируется переменной `features.config.location`).

* Запросом к config-серверу.
